Abstract

Field experiments were carried out at Agricultural Research Station, Vaigai Dam, to identify the performance of designer seed on yield of cotton. Seeds fortified with KCl 1% for 6 h followed by polymer coating @ 3ml/ kg + Carbendazim @ 2 g/kg + imidachloprid @ 2 ml/kg + Tichoderma viride @ 4 g/kg + Azospirilum @ 40 g /kg.  The effect was more beneficial through increased field emergence (86%) population at maturity/plot (57.34), number of sympodial branches (13.62), number of. bolls/ plant (64.50), kapas yield/plant (71.02 g),  kapas yield/plot (2.43 kg) and seed yield/ plant (43.72 g) compared to untreated control (73%, 48, 12.04, 50.99, 59.67 g, 1.93 kg and 37.9 g, respectively for field emergence, population at maturity/plot, number of sympodial branches, number of. bolls/ plant, kapas yield/plant (g),  kapas yield/plot (kg) and seed yield/ plant (g)) . Days to 50% flowering and pest and disease incidences (%) were higher in untreated control compared to control. The per cent decrease over control was 12.5 and 52.4%, respectively for days to 50 % flowering and pest and disease.
